Poor guy. Hope someone has taught you how to use a leakdown test. You did so much work. I am stoked at your determination... Gotta give you that
Just one question. If after you determined that fuel, and spark were fine, why not perform a cylinder leak down test , and that would determine if it was an intake or exhaust valve problem?
I don't have the tool for that test. Which i will be buying one soon
Great video!!
Thank you
sorry to be offtopic but does anybody know a trick to get back into an instagram account..?
I somehow forgot my account password. I would appreciate any tricks you can offer me
@Melvin Erik instablaster ;)
@Nova Silas Thanks so much for your reply. I found the site on google and im waiting for the hacking stuff now.
Takes quite some time so I will reply here later with my results.
@Nova Silas it worked and I now got access to my account again. Im so happy!
Thanks so much you really help me out!
Outstanding! Just subscribed, thanks
Thank you for your support! Glad it helped
Ok so are you saying that is not a collapsed lifter? Because mine is doing exactly the same thing. Also can you use a 12v test light instead of a noid light?
Yes you can use a test light. It was a burnt valve
Makes me feel like I understand my car a little more.
Hi.a2006 gmc yukon xl wen I put the obd 2 shows me evap not ready in have po306 I ready put a spark plugs and wires anf coil still have the code
2019 Ram 5.7 39k miles. P0307 misfire as well. 2 plugs and Coil Pack changed and I still a problem. Old spark plugs were very dark and had a lot of black residue.
Did you check compression. And did you move over the injectors
its burning too rich fuel injectors might be pumping out more fuel?
Faulty fuel injector
So i changed spark plug and ignition coil and wire. What should I do next. You think I should try the fuel injector? Cause I don't know what else to do
Start a diagnosis checklist and go down it for whatever code you have. Example: I have a 5.3L with p0300: - Tried:
Changed Spark, Wires, coils, MAF, air filter, intake manifold gasket, no air box leaks, tested o2 sensor for continuity (Good),
- Haven’t Tried: Fuel Filter, crankshaft relearn (Pro Scan-Tool), check fuel pressure, cylinder compression, cam & crank sensors,
I think he meant to say (4.8) 5.3 or 6.2 engines, not (4.3) 5.3 or 6.2 engines.
I sparkplug come out with gas??? Wharmt could be
Hey bro I have a 2007 gmc yukon 5.3 vortec I was driving to ramp on to the highway and got the rpms high about 4500rpm maybe 5000rpm and when I let off my check engine light started flashing and my stability light came on my car ran really rough and weak I was able to get it home and now when I start it the check engine light flashes and the stability light stays on ....ran the code it's p0300 ....no engine knocks no lifter knocks .....just random misfire......what could it be ?
Afm and DOD deleted you need bro, and tuned to v8 mode all the time
Have u fixed it? I’m having the same issue
8 cyl 6.0 L 02 cad ext loss of power. I have done, EGR pipe, valve, gas filter gas pump, oxy sensor ECM computer, plugs wires coils, compression test shows all pistons good. today going to throttle body position sensor. Every else checks out I am frikin stuck :( damn code reader still just says misfire.
crank relearn?
Exact same on my 04 yukon xl denali 6.0 - had computer guys on it, packs and injectors reading,o2 's reading good. Ds cat runnin hot around 800 , Ps runnin 2-300. Ps cylinders not firing right. The hot side cat we dropped exhaust of header in case it was plugged,loud but didnt run any better.cylinders psi checked @125lbs.neebwires,plugs,cam sensor, air filter,mass air flow,Im f-in stumped. Anyone?,
ok recap... So all that I wnet trough was the mechanic who was working onit. Told him bringhte truck to my yard, A diff guy came buy he looked at it for 3 minutes. started it .. took off the oil cap, ANd then said. Your cats are clogged. He cut them ff, welded straight pipe from manifolds Truck is like new. ( Ordered 2 new cats) Fn other mechanci cost me 1700 with his diagnostic measures.
I have an 07 Yukon Denali..6.2. I am getting code P0300 and I can figure it out. could it be this situation
Have you done any testing
@@JaboTheMechanic yes, I have changed coils, getting spark on all cylinders , while it’s running I plugged the coils and cylinders 5,7 & 8 where the only ones that changed the pitch of the engine. Took valve covers off and felt around on springs and rocker arms nothing felt broke.
Switch the injectors around to see if the issue follows the injectors that you swapped. And how are the spark plugs
Mass air flow, by the spray cleaner and see if that helps!!!
intake magnafol gaskets
or crank shaft sensor relearn
My truck is a 5.3, it runs fantastic but I cannot turn the a/c on because cylinder 7 will stop working and leak fuel, we’ve don’t spark plugs wires injectors O rings and coil packs and it still does it, if I don’t run the a/c the truck runs great, any ideas?
Under load-possible valve issue,fuel,plugs
@@Watchout1010 the motor was just under stress because my a/c compressor was shit and boggin my motor down causing it to miss
Even that intake runner is much cleaner. Could be due to your carb clean though.
Long story short leads nowhere
.
This was pointless..
Get to the point first then explain too long rambling
No offence but
You take to long to get to the point!
Like listing to a a woman!
Well gotta go into detail so other people can understand on what issue it can be.
If you don’t like it, then don’t watch it!!
Thanks for the support 🙏!
How do you know if you like it until you watch it ? And waiting for the answer forever is suspenseful more than anything.
Thanks for the supoort
straight to the fix
than explain how you figure it out
Please learn how to use the word “actually” WOW do you want to sound illiterate? Also, a tip do a baseline test first showing your audience the symptom, in this case P0307, this will help explain what you're trying to do.
